This question already has an answer here:
I have a Drupal 7 site that is creating a seemingly infinite stream of sub-directories creating a vast amount of duplicate content. For example:
example.com/test/ - is a legitimate page.
example.com/test/test/ - is a duplicate of the above, and this goes on and on like so:
example.com/test/test/test/test/test/test/test/test/test/test/test/test - etc etc.
All of these pages are crawlable and returning a 200 code. I'm not very familiar with Drupal and I can't pinpoint what is causing this. Any ideas?
